Introduction. Vitamin D deficiency may be an independent predictor of coronary heart disease (CHD) and the severity atherosclerosis. The results studies association various polymorphisms vitamin receptor ( VDR ) gene with risk CHD are contradictory, which necessitates study genetic variants characteristics clinical course in Russian population. objective was to determine distribution genotypes ...

the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

The GH gene and BMP15 gene have been used as candidate genes for ­marker-assisted selection in different livestock species. Random blood samples were obtained from 180 Zel sheep breed to study genetic polymorphism of these genes. DNA was extracted from blood samples and a 365 bp fragment from the exon V of the ovine growth hormone gene and a 312 bp region from exon II of BMP15 gene were amplifi...

Powdery mildew caused by Erysiphe necator, is one of the most economically damaging diseases of grapevine throughout the world. This is the first molecular biology study on this fungus in Iran. The aims of the present study were (a) to analyse genetic diversity between isolates of E. necator fungus in four main grape production regions in Iran, i. e., Qazvin, Alamoot, Takestan and Shahriar and ...

Objectives: This present study aims to understand the landscape structures as well environmental (climatic) factors influencing genetic diversity of fly populations in agroecological area Niayes. Methodology and results: Landscape composition different mango orchards typologies were determined after drone mapping samples carried out on Kent mangoes. The molecular biology process about fifty ind...

background: indigenous chickens could serve as precious genetic resources that should be considered in conservation and breeding programs. the major histocompatibility complex (mhc) has a strong association to disease resistance/susceptibility, production and reproduction traits in chicken. therefore, identifying its polymorphism in populations under selective breeding could be used for selecti...

The polymerase chain reaction and restriction fragment length polymorphism (RFLP) of the internal transcribed spacer (ITS) region of the rRNA gene, using the enzyme DdeI were used for the molecular identification of ten species and one subspecies of Brazilian Biomphalaria. Emphasis is given to the analysis of B. oligoza, B. schrammi and B. amazonica. The RFLP profiles obtained using this enzyme...

results the frequencies of the aa, at, and tt genotypes were 31%, 51%, and 18% in the chronic hbv patient group, and 40%, 45%, and 15% in the healthy control group, respectively. however, a lack of association of the + 874 polymorphism in the ifn-γ gene of those with chronic hbv infection was found. evaluation of hbv association with this polymorphism was significant under the dominant genetic ...
